COVER/TABLE TYPEWBITERS.

Application filed Februar a, 1927. Serial No. 166,660.

This invention is atypewriter accessory and is particularly intended for use on the well known No. 6 Remington-Noiseless typewriter. a p

In this machine, thewupper front shield is mounted on the forward'portion of the frame of the machineandthe upper type bar guide is spaced rearwardly therefrom an appreciable distance. Between these parts and slightly below the level of the tops thereof, the type bars are positioned in diverging relation. The type bar moveinents are, therefore,exposed at the top of the machine and directly betweenthe operator and the carriage. -This is a disadvantage for numerous reasons. For example it is essential to the proper "functioning o a Noiscless machine that it be kept Well lubr.i cated, i. e., that all parts thereof carry liberal supply of oil If this machine is llllbl'lCt'tlOCl with a liberal supply of oil, I have found that when the type actions are operated, oil is very apt to be throwncup wardly through the opening. between the front shield and the upper type bar guides.

and cause spattering of oil upon the sheet of paperin the carriage. It isj thereforenecessary 1n operating such" a machine to lubricate it sparingly, particularly as regards the type baractions and there is a. marked tendency to under lubricate these partstfor the reasons specified. Furthermore, my ex perience has shown me that the openspace provided inthis machine between the for ward edge of: the upper type barguide and the front shield permits considerable noise to come from the machine when in rapid operation.

lVith the foregoing in mind, the objeotiof the present invention is to provide ancover table for machines of the character: described and to construct such table that it will entirely cover and conceal the operations of the type her actions to which I have When such acover tableiis employed, -my experience has shown that 'it should be lined throughout witha suitable sound points where it would contact'with the front shield, the upper type bar, guides or the frame of the machine, it should be provided with gaskets which will preclude rattling or deadening material and at suchmetallic sounds due to Vibration between the related parts. h i i U Thecover table of this inventionis pref eraloly in the form of a sheet metal stamping, lined throughout with a sound deadenin material and adapted to be fitted to the o. 6 Remington-Noiselessmachine, so

as to beheld in lace by theconventional parts of the mac ine.. The table is made perfectly flat at its top and rests at its rear margin upon the up er type bar guides with a gasket interposed etween these parts. Its forward edge extends below the front shield oi themachine, anda gasket is interposed between said. marginal edge and the front shield, so that-the parts will not directly contactand cause rattling when the machine is in operation. The lateral portionsof the table are bent downwardly to overlie the normally open space between the front shield and type bar guides and flanges are formedon these sides of the table to permit it to be ;clamped in place.

- By making the table perfectly flat onits to 3, it will serveas a convenient means for a jost ing and alining papers in direct proxcarriage when the bail is thrownforward as 1s frequently done when adJusting papers 1n the machine or making erasures on carbon copies. The bail 18 adapted to slide freely over the face ofthe table if the machine is operated while the bail is in its. retracted position and cam surfaces are formed upon the table to cooperate with the rolls of such bail. so that the parts will not jam.

The structure is simple "and from a manufacturing standpoint may be economically produced. .It will materially lessen the noise incident to operation of the machine by precluding the exit-of sounds from the interior thereof. The lining of thetable will. preclude vibration thereof and serves also to catch any oilthatmay be thrown up fromqthe key actions. It is therefore. possible to fully and properly lubricate a inachine when the presentiinvention is assoiciated therewith as excess oil cannot pOs-M sibly be thrown upon the. papers in the carriage.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction withthe accompanying drawing.

The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a perspective view of a No; 6 Remington-Noiseless typewriter, with which the present invention is shown as associated. In this view, the greater portion of the machine is shown in dotted lines, and only the front shield. the uppentype bar guide and the cover table of this invention are illustrated in full lines.

Figure 2 is a perspective view of the cover table of this invention showing a portion of the cover table broken away to illustrate its sectional appearance and also showing the front shield and upper type bar guide of a conventional machine in cooperative, relation with the table and in vertical section.

Figure 3 is a section on the line 33 of Figure 2.

Referring to the drawings, 1 designates the frame of a'typewriter machine, here shown as a No. 6 RemingtonlNoiseless typewriter. This machine is well known to the art and is in wide application. necessary to describe details of the machine other than in so far as necessary to render the present invention fully undelstood.

' The machine shown in Figure 1 embodies the frame 1, carriage 2, a front shield 3,

and an upper type bar guide 4, sometimes called in the trade the comb guide.

A-ssociated with the carriage is the bail 5. This bail longitudinally graduated to assist in spacing papers in the carriage and is equipped with rollers 6, which bear upon the paper when the bail is in normal position. The bail is, however, mounted for pivotal movement on arms which permit it to be retracted from the carriage roller when it is desired to adjust the papers in the machine or to make erasures in carbon copies. In the machine as now built, the ball s adapted to be drawn forward on its pivot' connection referred to and to rest upon a' small upstandmg bracket mounted on the comb guide 4 and extending upwardly a suflicient distance'to preclude the rolls from engaging with the comb guide if the carriage as stated. v

In carrying out the present invention, I

entirely dispense with this bracket as it is unnecessary when the present invention is employed in this machine.

It will be noted from Figure 2 that the.

front shield 3 is spaced forwardlyof the comb guide 4 for anappreeiable distance It is not considered the bail is retracted and the type bar actions are mounted directly beneath this opening, so that in the conventional machine, they are visible as one looks down on the machine. Dust and dirt fall into the type actions through this opening and not infrequently eraser-s, pencils and other foreign materials fall into the action and unless immediately removed may cause damage thereto. 7

In accordance with the presentinvention, the opening towhich I have referred is entirely closed by means of a cover table 7. This table maybe in the form of a casting, if desired, but I find it thoroughly efficient and practical to employa sheet metal stamp ing in this connection. The table 7 is formed with a perfectly flattop 8, the forward inarginof which is adapted to underlie the rear edge of the frontshield. while the rear margin of the table overlies the comb guide 4. The flat top 8 is-of substantially segmental shape and at its radial edges is provided with depending sides 9 g of sufficient depth to extend downwardly to the top of the frame 1. As shown in Figure 2, the forward :portions of each side are adapted to extend Within the front shield and at the lower edge of this extending portion is a laterally extending ear or flange 10, adapted to underlie the cast attaching lugs 11 of the front shield, as shown in Figure 1. The ears 10 are perforated to register with the perforations in the lugs 11, so that when the front shield is secured 'in place by conventional screws, these screws will pass through the perforations 12 in the ears 10 and clamp the cover table ri idly to the machine. If desired, each site 9 may have a forward extension 14 carrying a laterally extending ear 15 adapted to reston the top of the corresponding attaching lug '16 of the comb guide,'so that the screws for securing the comb guide to the frame maybe passed through the cars 15 before extending through the lugs 16 and threading into the frame.

This latter construction is'shown in Figure 2, but it is omitted from Figure 1 in the table is lined with a sound absorbing Ina- This terial 17, such as felt, or the like. serves to dam vibration and render the 'structureas noiseless as possible. It will be underlies, so that there will be no metallic sounds resulting" from vibration between from striking against the table.

these parts. Similarly, .the'rear margin of the table is spaced above the comblguide'by a relatively :deep gasket 19. This gasket is of sufficient height to make the fiat 'top of the table substantially horizontal and furtherto space the table sufficiently above the comb guide as to preclude the type actions This is desirable since, in practice, these actions sometimes rebound to a point slightly above the plane ofthe top .of the comb guides.

To seal the gasket 19, the rear edge of the table is preferably flanged downwardly as shown at 20,:although in no case should this flange he of sufhcient :dep-th toengage with thecomb guide. since, if it did, relative vibration between these parts would cause rattling.

\Vheu the bail Sis retracted, as hereinbefore stated, it is adapted to rest upon the flat top of the table. The roller 6 carried by said bail will extend somewhat below the top of the table when the carriage is cent ally positioned and in order to preclude binding when the carriage is moved with the bail inflthisposition, the table is provided at each of its lateraledges with stamped out guide lugs 21, as shown best in Figures 2 and 3. These lugs are slightlyinclined and are positioned to'be in the direct path of travel of the roller 6. Thus, if the carriage is moved with the bail in forward position, the rollers 6 will engage the lugs 21- and cause the bail to be slightlyilifted to preclude binding or straightening on the "parts.

In Figure 1, the index pointer 22 is shown as delineated-on the tableZ, This takes the place of and serves the same purpose as the indication found on the bracket in the conventional machine, that is to say, it facilitates the placement of the carriage.

The cover table of this invention can be readily and expeditiously associated with a Remington-Noiseless #6 machine as it is only necessary to remove the few screws which hold the front shield and comb guide in place and to thereupon bring the cover table into "position and reinsert the screws. This will firmly bind the parts together. It will be apparent from the foregoing detailed description that the invention is of pronounced utility and merit. It precludes the falling of dirt or extraneous articles into the type actions, keeps the machine cleaner, renders it less noisy, and allows it to be properly lubricated without fear of soiling paper in the machine. The construction may be economical to manufacture and when enameled to correspond with the remaining portions of the machine which it cooperates, the device is aesthetic in appearance and materially adds to the appearance of the machine. The table, moreover, provides a convenient place to arrange papers immediately prior to their insertion into the machine and also precludes unauthorized persons from :tampering with the type her actions. The foregoing description sets forth the invention in its preferred practical form,

but the invention is to be understood as opening between the front shield and the comb guide of a Noiseless typewriter, with the forward margin of the plateextending beneath the rear margin ofth'e front shield and with the rear margin of the plate overlying the comb guide. flanges formed atthe lateral. edges of said plate and extending downwardly to the frame of the machine, attaching lugs formed on the sideiiangcs and adaptedto be secured to the machine by screws which secure conventional parts of the machine to the frame of such machine, sound deadening lining covering the inner face of the :ilatc audits flanges, and gaskets interposed between the plate and the front shield and the plate and the comb guide to preclude rattling between the plate and these parts.
